This is the intended use for this app. Go to the Learning tab. Here you can practice questions and reveal their answers at your own pace. Use icon to reveal answers. The answers will automatically hide after a few seconds. Take this time to memorize them. Then try putting the correct answer in.
When you are comfortable with a few questions, go to the Test tab where you test the items from the Learning tab. Each question you get correct is moved from the Learning tab to the Memorized tab. Rinse and repeat for all the questions you are interested in. Good Luck!Any question that is maybe too easy or out of your interest, you can click on the archive button to put it out of the learning category. The goal would be to get all the questions out of learning into memorized.
